* interrupts will not have execution priority. SVCall must have execution
|
||||
* priority in all cases.
|
||||
*
|
||||
* In the normal cases, interrupts are not nest-able and all interrupts run
|
||||
* at an execution priority between NVIC_SYSH_PRIORITY_MIN and
|
||||
* NVIC_SYSH_PRIORITY_MAX (with NVIC_SYSH_PRIORITY_MAX reserved for SVCall).

* If, in addition, CONFIG_ARCH_HIPRI_INTERRUPT is defined, then special

* high priority interrupts are supported. These are not "nested" in the

* normal sense of the word. These high priority interrupts can interrupt
|
||||
* normal processing but execute outside of OS (although they can "get back
|
||||
* into the game" via a PendSV interrupt).
|
||||
*
|
||||
* In the normal course of things, interrupts must occasionally be disabled
|
||||
* using the irqsave() inline function to prevent contention in use of
|
||||
* resources that may be shared between interrupt level and non-interrupt
|
||||
* level logic. Now the question arises, if CONFIG_ARCH_HIPRI_INTERRUPT,
|
||||
* do we disable all interrupts (except SVCall), or do we only disable the
|
||||
* "normal" interrupts. Since the high priority interrupts cannot interact
|
||||
* with the OS, you may want to permit the high priority interrupts even if
|
||||
* interrupts are disabled. The setting CONFIG_ARCH_INT_DISABLEALL can be
|
||||

* Description:
|

* On SPI buses where there are multiple devices, it will be necessary to

* lock SPI to have exclusive access to the buses for a sequence of

* transfers. The bus should be locked before the chip is selected. After

* setbits, and setmode methods to make sure that the SPI is properly
|

* configured for the device. If the SPI buss is being shared, then it
|
||||
* may have been left in an incompatible state.
|

*
|

* Input Parameters:
|

* dev - Device-specific state data
|

* lock - true: Lock spi bus, false: unlock SPI bus

Development Environment
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Either Linux or Cygwin on Windows can be used for the development environment.
|
||||
The source has been built only using the GNU toolchain (see below). Other
|
||||
toolchains will likely cause problems. Testing was performed using the Cygwin
|
||||
environment.
|
||||
|
||||
GNU Toolchain Options
|
||||
^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The NuttX make system has been modified to support the following different
|
||||
toolchain options.
|
||||
|
||||
1. The Code Red GNU toolchain
|
||||
2. The CodeSourcery GNU toolchain,
|
||||
3. The devkitARM GNU toolchain,
|
||||
4. The NuttX buildroot Toolchain (see below).
|
||||
|
||||
All testing has been conducted using the Code Red toolchain and the
|
||||
make system is setup to default to use the Code Red Linux toolchain. To use
|
||||
the other toolchain, you simply need add one of the following configuration
|
||||
options to your .config (or defconfig) file:
|
||||
|
||||
CONFIG_ARMV6M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
|
||||
CONFIG_ARMV6M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux
|
||||
CONFIG_ARMV6M_TOOLCHAIN_DEVKITARM=y : devkitARM under Windows
|
||||
CONFIG_ARMV6M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
||||
CONFIG_ARMV6M_TOOLCHAIN_CODEREDW=n : Code Red toolchain under Windows
|
||||
CONFIG_ARMV6M_TOOLCHAIN_CODEREDL=y : Code Red toolchain under Linux
|
||||
|
||||
You may also have to modify the PATH in the setenv.h file if your make cannot
|
||||
find the tools.
|
||||
|
||||
NOTE: the CodeSourcery (for Windows), devkitARM, and Code Red (for Windoes)
|
||||
are Windows native toolchains. The CodeSourcey (for Linux), Code Red (for Linux)
|
||||
and NuttX buildroot toolchains are Cygwin and/or Linux native toolchains. There
|
||||
are several limitations to using a Windows based toolchain in a Cygwin
|
||||
environment. The three biggest are:
|
||||
|
||||
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
|
||||
performed automatically in the Cygwin makefiles using the 'cygpath' utility
|
||||
but you might easily find some new path problems. If so, check out 'cygpath -w'
|
||||
|
||||
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links
|
||||
are used in Nuttx (e.g., include/arch). The make system works around these
|
||||
problems for the Windows tools by copying directories instead of linking them.
|
||||
But this can also cause some confusion for you: For example, you may edit
|
||||
a file in a "linked" directory and find that your changes had no effect.
|
||||
That is because you are building the copy of the file in the "fake" symbolic
|
||||
directory. If you use a Windows toolchain, you should get in the habit of
|
||||
making like this:
|
||||
|
||||
make clean_context all
|
||||
|
||||
An alias in your .bashrc file might make that less painful.
|
||||
|
||||
3. Dependencies are not made when using Windows versions of the GCC. This is
|
||||
because the dependencies are generated using Windows pathes which do not
|
||||
work with the Cygwin make.
|
||||
|
||||
MKDEP = $(TOPDIR)/tools/mknulldeps.sh
|
||||
|
||||
NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
|
||||
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
|
||||
-Os.
|
||||
|
||||
NOTE 2: The devkitARM toolchain includes a version of MSYS make. Make sure that
|
||||
the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
|
||||
path or will get the wrong version of make.
|
||||
|
||||
Code Red IDE
|
||||
^^^^^^^^^^^^
|
||||
|
||||
NuttX is built using command-line make. It can be used with an IDE, but some
|
||||
effort will be required to create the project.
|
||||
|
||||
Makefile Build
|
||||
--------------
|
||||
Under Linux Eclipse, it is pretty easy to set up an "empty makefile project" and
|
||||
simply use the NuttX makefile to build the system. That is almost for free
|
||||
under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty
|
||||
makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
|
||||
there is a lot of help on the internet).
|
||||
|
||||
Native Build
|
||||
------------
|
||||
Here are a few tips before you start that effort:
|
||||
|
||||
1) Select the toolchain that you will be using in your .config file
|
||||
2) Start the NuttX build at least one time from the Cygwin command line
|
||||
before trying to create your project. This is necessary to create
|
||||
certain auto-generated files and directories that will be needed.
|
||||
3) Set up include pathes: You will need include/, arch/arm/src/lpc11xx,
|
||||
arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
|
||||
4) All assembly files need to have the definition option -D __ASSEMBLY__
|
||||
on the command line.
|
||||
|
||||
Startup files will probably cause you some headaches. The NuttX startup file
|
||||
is arch/arm/src/lpc11x/lpc11_vectors.S.
|
||||
|
||||
Using Code Red GNU Tools from Cygwin
|
||||
------------------------------------
|
||||
|
||||
Under Cygwin, the Code Red command line tools (e.g., arm-non-eabi-gcc) cannot
|
||||
be executed because the they only have execut privileges for Administrators. I
|
||||
worked around this by:
|
||||
|
||||
Opening a native Cygwin RXVT as Administrator (Right click, "Run as administrator"),
|
||||
then executing 'chmod 755 *.exe' in the following directories:
|
||||
|
||||
/cygdrive/c/nxp/lpcxpreeso_3.6/bin, and
|
||||
/cygdrive/c/nxp/lpcxpreeso_3.6/Tools/bin
|
||||
|
||||
Command Line Flash Programming
|
||||
------------------------------
|
||||
|
||||
During the port development was used a STLink-v2 SWD programmer with OpenOCD to
|
||||
write the firmware in the flash and GDB to debug NuttX initialization.
|
||||
|
||||
If using LPCLink as your debug connection, first of all boot the LPC-Link using
|
||||
the script:
|
||||
|
||||
bin\Scripts\bootLPCXpresso type
|
||||
|
||||
where type = winusb for Windows XP, or type = hid for Windows Vista / 7.
|
||||
|
||||
Now run the flash programming utility with the following options
|
||||
|
||||
flash_utility wire -ptarget -flash-load[-exec]=filename [-load-base=base_address]
|
||||
|
||||
Where flash_utility is one of:
|
||||
|
||||
crt_emu_lpc11_13 (for LPC11xx or LPC13xx parts)
|
||||
crt_emu_cm3_nxp (for LPC11xx parts)
|
||||
crt_emu_a7_nxp (for LPC21/22/23/24 parts)
|
||||
crt_emu_a9_nxp (for LPC31/32 and LPC29xx parts)
|
||||
crt_emu_cm3_lmi (for TI Stellaris parts)
|
||||
|
||||
wire is one of:
|
||||
|
||||
(empty) (for Red Probe+, Red Probe, RDB1768v1, or TI Stellaris evaluation boards)
|
||||
-wire=hid (for RDB1768v2 without upgraded firmware)
|
||||
-wire=winusb (for RDB1768v2 with upgraded firmware)
|
||||
-wire=winusb (for LPC-Link on Windows XP)
|
||||
-wire=hid (for LPC-Link on Windows Vista/ Windows 7)
|
||||
|
||||
target is the target chip name. For example LPC1343, LPC1114/301, LPC1115 etc.
|
||||
|
||||
filename is the file to flash program. It may be an executable (axf) or a binary
|
||||
(bin) file. If using a binary file, the base_address must be specified.
|
||||
|
||||
base_address is the base load address when flash programming a binary file. It
|
||||
should be specified as a hex value with a leading 0x.
|
||||
|
||||
Note:
|
||||
- flash-load will leave the processor in a stopped state
|
||||
- flash-load-exec will start execution of application as soon as download has
|
||||
completed.
|
||||
|
||||
Examples
|
||||
To load the executable file app.axf and start it executing on an LPC1158
|
||||
target using Red Probe, use the following command line:
|
||||
|
||||
crt_emu_cm3_nxp -pLPC1158 -flash-load-exec=app.axf
|
||||
|
||||
To load the binary file binary.bin to address 0x1000 to an LPC1343 target
|
||||
using LPC-Link on Windows XP, use the following command line:
|
||||
|
||||
crt_emu_lpc11_13_nxp -wire=hid -pLPC1343 -flash-load=binary.bin -load-base=0x1000
|
||||
|
||||
tools/flash.sh
|
||||
--------------
|
||||
|
||||
All of the above steps are automated in the bash script flash.sh that can
|
||||
be found in the configs/lpcxpresso/tools directory.
|
||||
|
||||
NuttX EABI "buildroot" Toolchain
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
|
||||
be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
|
||||
different from the default in your PATH variable).
|
||||
|
||||
If you have no Cortex-M0 toolchain, one can be downloaded from the NuttX
|
||||
SourceForge download site (https://sourceforge.net/projects/nuttx/files/).
|
||||
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
||||
|
||||
1. You must have already configured Nuttx in <some-dir>/nuttx.
|
||||
|
||||
cd tools
|
||||
./configure.sh lpcxpresso-lpc1115/<sub-dir>
|
||||
|
||||
2. Download the latest buildroot package into <some-dir>
|
||||
|
||||
3. unpack the buildroot tarball. The resulting directory may
|
||||
have versioning information on it like buildroot-x.y.z. If so,
|
||||
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
|
||||
|
||||
4. cd <some-dir>/buildroot
|
||||
|
||||
5. cp configs/cortexm0-eabi-defconfig-4.6.3 .config
|
||||
|
||||
6. make oldconfig
|
||||
|
||||
7. make
|
||||
|
||||
8. Edit setenv.h, if necessary, so that the PATH variable includes
|
||||
the path to the newly built binaries.
|
||||
|
||||
See the file configs/README.txt in the buildroot source tree. That has more
|
||||
details PLUS some special instructions that you will need to follow if you
|
||||
are building a Cortex-M3 toolchain for Cygwin under Windows.
|
||||
|
||||
NOTE: Unfortunately, the 4.6.3 EABI toolchain is not compatible with the
|
||||
the NXFLAT tools. See the top-level TODO file (under "Binary loaders") for
|
||||
more information about this problem. If you plan to use NXFLAT, please do not
|
||||
use the GCC 4.6.3 EABI toochain; instead use the GCC 4.3.3 OABI toolchain.
|
||||
See instructions below.
|
||||
|
||||
NuttX OABI "buildroot" Toolchain
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The older, OABI buildroot toolchain is also available. To use the OABI
|
||||
toolchain:
|
||||
|
||||
1. When building the buildroot toolchain, either (1) modify the cortexm3-eabi-defconfig-4.6.3
|
||||
configuration to use EABI (using 'make menuconfig'), or (2) use an exising OABI
|
||||
configuration such as cortexm3-defconfig-4.3.3
|
||||
|
||||
2. Modify the Make.defs file to use the OABI conventions:
|
||||
|
||||
+CROSSDEV = arm-nuttx-elf-
|
||||
+ARCHCPUFLAGS = -mtune=cortex-m3 -march=armv6-m -mfloat-abi=soft
|
||||
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections
|
||||
-CROSSDEV = arm-nuttx-eabi-
|
||||
-ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
|
||||
-NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections
|
||||
|
||||
NXFLAT Toolchain
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
If you are *not* using the NuttX buildroot toolchain and you want to use
|
||||
the NXFLAT tools, then you will still have to build a portion of the buildroot
|
||||
tools -- just the NXFLAT tools. The buildroot with the NXFLAT tools can
|
||||
be downloaded from the NuttX SourceForge download site
|
||||
(https://sourceforge.net/projects/nuttx/files/).
|
||||
|
||||
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
||||
|
||||
1. You must have already configured Nuttx in <some-dir>/nuttx.
|
||||
|
||||
cd tools
|
||||
./configure.sh lpcxpresso-lpc1115/<sub-dir>
|
||||
|
||||
2. Download the latest buildroot package into <some-dir>
|
||||
|
||||
3. unpack the buildroot tarball. The resulting directory may
|
||||
have versioning information on it like buildroot-x.y.z. If so,
|
||||
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
|
||||
|
||||
4. cd <some-dir>/buildroot
|
||||
|
||||
5. cp configs/cortexm0-defconfig-nxflat .config
|
||||
|
||||
6. make oldconfig
|
||||
|
||||
7. make
|
||||
|
||||
8. Edit setenv.h, if necessary, so that the PATH variable includes
|
||||
the path to the newly builtNXFLAT binaries.
|
||||
|
||||
LEDs
|
||||
^^^^
|
||||
|
||||
If CONFIG_ARCH_LEDS is defined, then support for the LPCXpresso LEDs will be
|
||||
included in the build. See:
|
||||
|
||||
- configs/lpcxpresso-lpc1115/include/board.h - Defines LED constants, types and
|
||||
prototypes the LED interface functions.
|
||||
|
||||
- configs/lpcxpresso-lpc1115/src/lpcxpresso_internal.h - GPIO settings for the LEDs.
|
||||
|
||||
- configs/lpcxpresso-lpc1115/src/up_leds.c - LED control logic.
|
||||
|
||||
The LPCXpresso LPC1115 has a single LEDs (there are more on the Embedded Artists
|
||||
base board, but those are not controlled by NuttX). Usage this single LED by NuttX
|
||||
is as follows:
|
||||
|
||||
- The LED is not illuminated until the LPCXpresso completes initialization.
|
||||
|
||||
If the LED is stuck in the OFF state, this means that the LPCXpresso did not
|
||||
complete initializeation.
|
||||
|
||||
- Each time the OS enters an interrupt (or a signal) it will turn the LED OFF and
|
||||
restores its previous stated upon return from the interrupt (or signal).
|
||||
|
||||
The normal state, after initialization will be a dull glow. The brightness of
|
||||
the glow will be inversely related to the proportion of time spent within interrupt
|
||||
handling logic. The glow may decrease in brightness when the system is very
|
||||
busy handling device interrupts and increase in brightness as the system becomes
|
||||
idle.
|
||||
|
||||
Stuck in the OFF state suggests that that the system never completed
|
||||
initialization; Stuck in the ON state would indicated that the system
|
||||
intialialized, but is not takint interrupts.
|
||||
|
||||
- If a fatal assertion or a fatal unhandled exception occurs, the LED will flash
|
||||
strongly as a slow, 2Hz rate.
|
||||
|
||||
LPCXpresso Configuration Options
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
General Architecture Settings:
|
||||
|
||||
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
|
||||
be set to:
|
||||
|
||||
CONFIG_ARCH=arm
|
||||
|
||||
CONFIG_ARCH_family - For use in C code:
|
||||
|
||||
CONFIG_ARCH_ARM=y
|
||||
|
||||
CONFIG_ARCH_architecture - For use in C code:
|
||||
|
||||
CONFIG_ARCH_CORTEXM0=y
|
||||
|
||||
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
|
||||
|
||||
CONFIG_ARCH_CHIP=lpc11xx
|
||||
|
||||
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
|
||||
chip:
|
||||
|
||||
CONFIG_ARCH_CHIP_LPC1115=y
|
||||
|
||||
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
|
||||
hence, the board that supports the particular chip or SoC.
|
||||
|
||||
CONFIG_ARCH_BOARD=lpcxpresso-lpc1115
|
||||
|
||||
CONFIG_ARCH_BOARD_name - For use in C code
|
||||
|
||||
CONFIG_ARCH_BOARD_LPCEXPRESSO=y
|
||||
|
||||
CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
|
||||
of delay loops
|
||||
|
||||
CONFIG_ENDIAN_BIG - define if big endian (default is little
|
||||
endian)
|
||||
|
||||
CONFIG_RAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
|
||||
|
||||
CONFIG_RAM_SIZE=(8*1024) (8Kb)
|
||||
|
||||
There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
|
||||
|
||||
CONFIG_RAM_START - The start address of installed DRAM
|
||||
|
||||
CONFIG_RAM_START=0x10000000
|
||||
|
||||
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
|
||||
have LEDs
|
||||
|
||||
CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
|
||||
stack. If defined, this symbol is the size of the interrupt
|
||||
stack in bytes. If not defined, the user task stacks will be
|
||||
used during interrupt handling.
|
||||
|
||||
CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
|
||||
|

CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to board architecture.
|
||||
|
||||
CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
|
||||
cause a 100 second delay during boot-up. This 100 second delay
|
||||
serves no purpose other than it allows you to calibratre
|
||||
CONFIG_ARCH_LOOPSPERMSEC. You simply use a stop watch to measure
|
||||
the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
|
||||
the delay actually is 100 seconds.
|
||||
|
||||

Configurations
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
Each LPCXpresso configuration is maintained in a sub-directory and can be
|
||||
selected as follow:
|
||||
|
||||
cd tools
|
||||
./configure.sh lpcxpresso-lpc1115/<subdir>
|
||||
cd -
|
||||
. ./setenv.sh
|
||||
|
||||
Where <subdir> is one of the following:
|
||||
|
||||
dhcpd:
|
||||
This builds the DCHP server using the apps/examples/dhcpd application
|
||||
(for execution from FLASH.) See apps/examples/README.txt for information
|
||||
about the dhcpd example.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. To
|
||||
change this configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
and misc/tools/
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Jumpers: Nothing special. Use the default base board jumper
|
||||
settings.
|
||||
|
||||
nsh:
|
||||
Configures the NuttShell (nsh) located at apps/examples/nsh. The
|
||||
Configuration enables both the serial and telnet NSH interfaces.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. To
|
||||
change this configurations using that tool, you should:
|

||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. This configuration has been used for testing the microSD card.
|
||||
This support is, however, disabled in the base configuration.
|
||||
|
||||
At last attempt, the SPI-based mircroSD does not work at
|
||||
higher fequencies. Setting the SPI frequency to 400000
|
||||
removes the problem. There must be some more optimal
|
||||
value that could be determined with additional experimetnation.
|
||||
|
||||
Jumpers: J55 must be set to provide chip select PIO1_11 signal as
|
||||
the SD slot chip select.
|
||||
|
||||
nx:
|
||||
And example using the NuttX graphics system (NX). This example
|
||||
uses the UG-9664HSWAG01 driver.

* Description:
|
||||
* The external functions, lpc17_ssp0/ssp1select and lpc17_ssp0/ssp1status
|
||||
* must be provided by board-specific logic. They are implementations of the select
|
||||
* and status methods of the SPI interface defined by struct spi_ops_s (see
|
||||
* include/nuttx/spi/spi.h). All other methods (including lpc17_sspinitialize())
|
||||
* are provided by common LPC17xx logic. To use this common SPI logic on your
|
||||
* board:
|
||||
*
|
||||
* 1. Provide logic in lpc17_boardinitialize() to configure SPI/SSP chip select
|
||||
* pins.
|
||||
* 2. Provide lpc17_ssp0/ssp1select() and lpc17_ssp0/ssp1status() functions
|
||||
* in your board-specific logic. These functions will perform chip selection
|
||||
* and status operations using GPIOs in the way your board is configured.
|
||||
* 3. Add a calls to lpc17_sspinitialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by lpc17_sspinitialize() may then be used to bind the
|
||||
* SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).
